• Check local codes, the installation mustcomply with them.

• The heater must be installed with strictconformance in regard to clearances.

• Connect the heater to a tile lined insidemasonry chimney or an approved, insulated,all fuel prefabricated chimney only.

• Do not connect to a flue serving a gas-firedappliance. (There is possible risk ofasphyxiation.)

• Keep the smoke pipe connection as short aspossible using a minimum 12” rise from theflue collar to the chimney opening.

• Be sure there is sufficient supply ofcombustion air to the area where the heateris to be located.

• Do not over draft the heater! It is designed tooperate at .04 to .06 inches of water column,and must be set with a draft gauge tomaintain a steady draft.

• Do not use flammable liquids for starting afire.

• Do not store fuel or combustibles near theheater. Some areas of the heater are hot andcould cause an explosion, and possible bodilyor property damage.

• Store all ashes in a metal container with atight sealing lid, and allow ashes to coolbefore disposing of them.

• The heater has hot surfaces. Keep childrenaway.

• The heater is designed to burn 20% air-driedwood at a pre-determined firing rate. Overfiring could result in damage and causedangerous operation.

• Follow a regular service and maintenanceschedule of the heater and chimney forefficient and safe operation.

• Do not leave the ash drawer open when thefire is burning.

• Familiarize yourself with the heater’s woodburning characteristics before leaving unitunattended for long periods of time.

• The fire door and ash drawer must be tightlyclosed during heater operation to insuresafety and efficiency.

• In the event of a chimney fire, call the firedepartment. Be sure the heater door isclosed tightly and the combustion air is turnedoff.

RULES FOR SAFE INSTALLATION AND OPERATIONOF YOUR NIPPA SAUNA HEATER

Page 4: Sauna Stoves Sauna Stoves Sauna Stoves Sauna Stoves & Heaters & Heaters & Heaters & Heaters

Page 3

SAUNA HEATER ASSEMBLY ANDINSPECTIONYour new sauna heater comes from the factorycompletely assembled and only requires you toinstall the rocks. At times, shipping damagedoes occur, therefore, inspect your heaterthoroughly upon arrival. If you find aquestionable area, speak to the delivery agent.He/she will take the necessary steps tocorrect the problem.

SAUNA HEATER LOCATIONInstalling a wood burning sauna heater requiresmore consideration than other types of heater.The safety, as well as efficiency of the woodburner’s operation, relies greatly on theminimum clearance to combustibles, ventilationof the sauna, and the chimney system.

Clearance ChartFrom Sauna Heater to: Protected Wall* Unprotected Wall

The side wall 13 inches 42 inchesThe back wall 17 inches 36 inchesThe front wall 48 inches 48 inches

Note: The smoke pipe at any point must not be closer than 18 inches to acombustible wall.*The wall protection indicated in this chart is illustrated in Figures 2 and 3.

It is a mistake to assume that sheet metal,masonry, or asbestos board placed directlyagainst a wall protect it. Materials installed inthis manner give very little protection. Thesematerials are good heat conductors, so they willbe almost as hot on their backside as well ason the exposed side. Therefore, thecombustible wall behind is still a fire hazard.A wall can be kept cool using ¼” cementasbestos board but only if it’s mounted andspaced out from the wall as shown in Figure 2to allow free circulation of room air behind theprotective panel. Circulating air keeps the wallcool by carrying the heat from the space

MINIMUM CLEARANCE TOCOMBUSTIBLE MATERIALYour sauna heater has been tested todetermine the safe clearances to combustiblematerial, and they are summarized in thefollowing chart and shown in Figures 1 and 2.

REDUCED CLEARANCESReduced clearances are allowed if areabetween the heater and combustible walls areprotected according to NFPA values. The NFPAis: National Fire Protection Association

60 Batterymarch StreetBoston, MA 02269-9101

between wall and panel. The protective panelshould start within a few inches of floor level.(See Figure 3)

Three rules to follow when constructing wallprotectors:

1. Non-combustibility of all materials includingmounting system.

2. A well ventilated air space between protectorand wall.

3. Sufficient strength and rigidity so that theprotector and air space will be durable.

In addition to the wall clearances, the floor must also be given special consideration. The heater must be placed on a noncombustible floor system of at least the size specified in Figure 4. The noncombustible floor may be a typical concrete basement floor at least four (4) inches thick.

For Models with the Extension

Follow the clearances and NONCOMBUSTIBLE wall requirements as shown in “Safe Wood Stove Installation with 6", 8" or 12" Extension”. This will apply to 10” Extensions as well.

SAUNA VENTILATION With the heater being installed in a closed area, like a sauna, you must provide for enough fresh air to assure proper combustion. Install two (2) 6” x 9” grilles in the sauna. One near the heater and one near the ceiling opposite the heater. This will provide enough air to ventilate the sauna and supply the heater.

THE CHIMNEY SYSTEMThe chimney system consists of all the partsnecessary to vent your sauna heater to theoutside. This would include the chimney itself,smoke pipe and chimney dampers.

THE CHIMNEYThe chimney, which must be used, is a Class A,all fuel chimney being six (6) or seven (7)inches in diameter. These chimneys includemasonry chimneys, which are tile lined, andalso many metal chimneys, which are listed forall fuel. (Typically triple wall or double wallinsulated).

When installing a new chimney, it isrecommended that it be placed within thestructure, rather than running up along theoutside. These interior chimneys remainwarmer and tend to have less creosote build upand fewer over all problems.

Before deciding to use an existing chimney,have it inspected by the building inspector orfire department for its suitability for use withyour sauna heat. Also when using anychimney, make sure it’s not further than eight(8) feet from the sauna heater. This willeliminate any fire hazard from having thesmoke pipe run too long. (Over eight (8) feet istoo long)!

Figures 6 and 7 show the typical ventingarrangements used. Metal chimneys areshown, however, the theories apply to masonrychimneys as well.

INSTALLING THE SMOKE PIPEThe smoke pipe is not a chimney. Its functionis to connect the sauna heater to the chimney.The smoke pipe you use should be not less that24-gauge steel. When planning your chimneyhookup, make sure a minimum of smoke pipeelbows are used two (2) or less, and that ahorizontal run of smoke pipe does not exceedeight (8) feet. The smoke pipe must not beinstalled closer than 18 inches to anycombustible materials or pass through acombustible wall or ceiling.

When attaching the smoke pipe to the heater,use a minimum of three (3) sheet metal screwsat each joint. This includes the joint at thesauna heater flue collar. For added protection,you may want to use furnace cement to helpseal each joint.

MANUAL DAMPERS IN THE STOVEPIPEIt is recommended that a manual damper beinstalled at a safe, convenient place betweenthe sauna heater and chimney. In the event ofa chimney fire, it can quickly be closed,reducing air to the chimney.

CAUTIONNever use chemicals or fluids such as

gasoline, charcoal lighter fluid, drain oilor kerosene to light a fire in your heater.This would be like checking the level of

gas in your gas can with a lighted match.

Place several pieces of paper and some smalldry kindling inside the unit. Ignite the paper andclose the door.

It will take a few minutes for the fire to establishitself. Once you have some good red hotburning embers, add larger pieces of wood. Allchimneys and hook-ups act differently. After awhile, you will find out how your unit works bestfor starting.

After a time, you can adjust draft according toyour needs. On air tight units, the burning timeis controlled very much by the draft control,contrary to the old type stove where the smokepipe damper controlled the burning time. Yourheater is capable of putting out a lot of heat sodon’t fully load your unit or open all draft fullyuntil you have become familiar with theoperation of the heater. Keep in mind; a fullload will not always give you the best results foryour needs. Note: With new metal – you maysmell an odor. This is normal during the firstoperation.

When loading your heater that has existing hotcoals, rake the red-hot embers over gratesevenly. Put a few smaller pieces of wood oncoals first, then load up. Close fuel door. Note:After several days of lengthy burn, load unit,open draft controls and burn your unit hot forabout 15 minutes while in attendance.

This is a good way to eliminate excessivecreosote build up.

Use Caution when opening loading door. Avoidopening-loading door rapidly. This could causeflame to flash out the door. This occurs whenthere is fuel that has not been burned, creatinga large amount of gases on top of the firebox.When the door is opened, oxygen is combinedwith the gases and ignites.

HELPFUL HINTSSet the draft to proper setting. The chimney,hookups and kinds of wood will be a factor.

Your heater is capable of holding very largelogs. Do not try to add a log that is larger thanwhat you can easily place in the firebox. Youwill get best efficiency when you add only theamount of wood needed for a short burn.

In the spring and fall when the weather is mild,burning large loads of wood for long periodsmay cause creosote. Stack temperature shouldbe 200 – 300 for good burning. An inexpensiveoven thermometer that reads 100 – 500 workswell for finding stack temperatures. Werecommend you install one to your smoke pipe.

You can use wood of various shapes, diametersand lengths, but not to exceed your unitspecification.

Always try to place the logs so air has free flowbetween them – increasing combustion.

ASH REMOVALOnce every week or two, depending on howmuch fuel you burn, ashes should be removed.

CAUTIONNever let ashes build up to a grate level.

This will reduce the life span of yourgrate.

To remove ashes, simply pull out your ash pan.But remember, the ash pan can get very hot.Dump ashes in a metal container with a lid thatis placed on a noncombustible surface.

CAUTIONNever use anything but a metal container

to put your ashes in. Emptying ashesinto cardboard boxes or paper bags

causes fires every year.

MAINTENANCEAt the start of the heating season:

• It is advisable to have your local furnace maninspect and service your heater for theupcoming heating season.

• The furnace, smoke pipe and chimney shouldbe cleaned and checked for repairs.

Grates – Keep ash pan empty. Failure to do

this can cause grates to warp.

Once a week let your heater burn with ashdrawer open for 15 minutes, not unattended.This will help to minimize creosote build up.

Smoke Pipe, Chimney – Do not burn green orfreshly felled wood. It you do, creosote andsoot may build up in the chimney and smokepipe. This should be checked and cleanedtwice monthly.

CLEANING THE CHIMNEY ANDSMOKE PIPEOn a regular schedule, twice monthly, check forcreosote and soot build up in the chimney andsmoke pipe. They must be kept clean.

Steel brushes are the safest for cleaning metalsurfaces. Salt solutions and some chemicalsmay damage metal surfaces. When cleaningchimney, obtain a stiff steel brush with anextension handle and insert brush into chimneyfrom the top. Continue brushing and sweepingdownward until the full length of the chimney iscleaned. Open the clean out door at the bottomof the chimney and sweep the debris into aplastic bag or container. When cleaning thesmoke pipe, use a steel brush.

WARNINGIn Case of Chimney Fire

1. Alert everyone in the house.

2. Call the Fire Department immediately.

3. Shut any doors and air inlet dampers and draft control. This should take no longer than afew seconds.

Do not use your heater until a professional inspection has been made of your heater, smokepipe and chimney.

CREOSOTE – FORMATION AND NEED FOR REMOVAL

When wood is burned slowly, it produces tar and other organic vapors, which combine withexpelled moisture to form creosote. The creosote vapors condense in the relatively coolchimney flue of a low burning fire. As a result, creosote residue accumulates on the fluelining. When ignited, this creosote makes an extremely hot fire.

The chimney connector and chimney should be inspected at least twice monthly during theheating season to determine if a creosote build up has occurred.

If creosote has accumulated, it should be removed to reduce the risk of a chimney fire.

Page 10: Sauna Stoves Sauna Stoves Sauna Stoves Sauna Stoves & Heaters & Heaters & Heaters & Heaters

The stove pipe for a sauna stove is located on the OUTSIDE of the flue, which avoids

water getting into the stove when pouring water onto the rocks!

Stove pipe for a room heater or wood stove is located on the INSIDE of the flue, allowing creosote to flow downward.

Stove pipe for a sauna stove should be standard black pipe. To flatten the “Pittsburg

Seam” on the first section, join the tube at the seam, lay it flat on a hard surface and using a hammer, pound the seam about 1 ½” up from the crimped end. This will still be a tight

fit, but will allow the pipe to fit OVER the flue.

If you wish to use insulated pipe for a sauna stove, the first course must be standard black pipe. Insulated pipe will not fit on the outside of the flue.

Wood stoves or room heaters may use insulated pipe OR standard black pipe.

At the ceiling for either stoves remember to use insulated pipe fittings!
